Material Designer has the ability to make a representative volume element unidirectional fiber geometry. The "Variable Material" analysis further provides the ability of computing mechanical property tables as a function of the fiber volume fraction. This seems to me like a "do-loop" or "for-loop" that is being run in the background over the volume fraction parameter. Is there a way to vary other properties besides the volume fraction, such as the mesh size, material, and temperature? My hope is to set up arrays of different values of these parameters, then be able to walk away while the analysis runs for a couple of days. Thanks in advance for any suggestions.

Hi, Once you have defined your RVE using MaterialDesigner or any other CAE software (you can have a look to Discovery as well, having great capibilities for archtiectured materials –> nanolattices…), you can parametrize your model using for example MAPDL, or the pyAnsys libraries available here: https://mapdl.docs.pyansys.com/version/stable/
Another solution is to set up parametric analysis using Workbench:
And if you want to have an optimisation of multiple parameters, Optislang is the solution: https://www.ansys.com/products/connect/ansys-optislang

Thanks, David - this gives me some useful information. I would really like to stick with MaterialDesigner, since it has some great capabilities for what I am trying to do. Is there somewhere I could go to to find a simple example of either APDL or Python code or a parametric study that is capable of 1) Changing a parameter (such as the mesh size) and 2) solving for the new mechanical properties, all within MaterialDesigner (not in static structural or discovery)? Thanks again for your help.
